TEMPORARY BINDER.

Specification of Letters Patent.

Patented Oct. 7, 1913.

Application filed January 22, 1912, Serial No. 672,679. Renewed August 26, 1913. Serial No. 786,800.

To all whom, it may concern:

Be it known that I, EDWARD J. SONNEN- BURG, a citizen of the United States, residing at Riverside, in county of. Riverside and State of California, have invented certain new and useful Improvements in Temporary Binders, of which the following is a specification.

My invention relates to an improvement in temporary binders, and the object is to provide a body made in two sections which are telescopic, and means for locking the sections together and holding them apart at any distance required for the binding of loose leaves therebetween.

A further object is in the provision of flexible tapes which are connected to the two body sections, and which tapes are always held in a taut position, no matter how far apart the two sections are from each other, or how close they may be drawn toward each other.

The invention further consists in certain other novel features of construction and combinations of parts which will be hereinafter described and pointed out in the claims.

In the accompanying drawings :Figure 1 is a top plan view, Fig. 2 is a side elevation with a portion broken away to disclose some of the interior mechanism, Fig. 3 is an end view, Fig. 4 is a view on the line 4.4 of Fig 1, Fig. 5 is a detail view partly in section showing the rod and sleeve and the means for fastening the rod and sleeve together, and Fig. 6 is an enlarged detail showing the clamp in end elevation which looks the sleeve and shaft together.

A and B represent the two sides or telescopic sections of the binder which are adapted to fit one within the other, and 1 and 2 are the ends of the sides A and B for forming closures at the end of the binder. Sleeves 3, 3, are connected along the inner wall of the section A, and rods 4, 4, are connected to the inner wall of the section or member B. The rods 4. are adapted to be received within the sleeves. Brackets 5, 5, are connected to the outer edge of the base or back of the section A for supporting the outer ends of the sleeves 3. The outer ends of the sleeves 3 are preferably split making them contractible. Clamps or collars 6 are mounted upon the split portions of the sleeves 3 and the upper ends of the clamps are provided with screw-threaded openings through which the screw-shaft 7 extends. The shaft 7 extends longitudinally of the binder and passes through each of the clamps having the several sleeves. Mounted upon the shaft and along one side of the clamps 6 are nuts 8 for holding one of the ends of the clamps against movement upon the turning of the shaft. A lock-nut 9 is mounted on the shaft, and against each nut 8 for locking the nuts in position upon the screw-shaft. An arm or lever 10 is formed on one end of the screw-shaft which passes through an elongated slot 11 in one of the ends 1 of the member B. When this lever is turned in one direction, the shaft will be rotated causing the ends of the clamps 6 to be drawn together for contracting the split portion of the sleeves 3 for fastening the sleeves and rods together, but when the lever is turned in the opposite direction, the split portion of the sleeve will be released and allowed to expand, whereby the rod can he moved freely within the sleeve by drawing the member B outward or away from the member A, and the releasing of the clamps on the rod and sleeve also permits the two members to be forced closer together. When the members are drawn apart or forced together, the elongated slot 11 relieves any obstruction which might be caused by the lever passing through the end 1.

J ournaled in brackets 12 formed along the upper edge of the member A is a shaft 13 which is provided with rollers 14:. Flexible tapes 15 are connected at predetermined intervals to the upper edges of the member B and pass over the space intervening between the two members, and over the rollers 14: on the rod 13, thence down between the two members and over rollers 16, carried on shaft 17 journaled along the outer edge of the base of the member A, and thence the tapes pass to the outer edge of the base of the member B where they are again connected.

It will be seen from the foregoing that the tapes will always remain taut, no matter what position the members A and B are in with respect to each other, and the position or relation of the members A and B with respect to each other is governed by the screw-shaft 7 that is, the screw-shaft when turned in one position allows the members to be either moved toward or from each other, but when the lever or arm is thrown to another position, the clamps 6 are drawn tightly around the split end of the sleeve 3, causing the split end to be contracted for binding the rods 4 thereto, and when the rods and sleeves are bound together, the members A and B are immovable.

The flexible tapes 15 form the means for supporting removable leaves between V the sides and holding the leaves in the binder when the members are moved apart for the insertion of additional leaves or the r moval of some of the leaves which have been previously bound in the binder.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A temporary binder comprising two members movably connected together, contractible sleeves connected to one of the members and rods connected to the other member adapted to be received in the ends of the contractible sleeves, and means for clamping the contractible sleeves to the rods for locking the members against movement.

2. A temporary binder comprising two members movably connected together, contractible sleeves connected to one member, rods connected to the other member and received in the contractible sleeves, clamps engaging the contractible sleeves, and means for actuating the clamps whereby the cont-ractible sleeves will be caused to engage the rods for locking the members against movement.

3. A temporary binder comprising two members movably connected together, contractible sleeves connected to one member, rods connected to the other member and received in the contractible sleeves, clamps engaging the contractible sleeves, a screw- 4 threaded shaft engaging the clamps, and means for operating the shaft whereby the clamps are caused to engage the contractible sleeves and cause the sleeves to engage the rods for locking the members against movement.

4-. A temporary binder comprising two members movably connected together, and flexible means for holding the leaves connected to one member and passing about the other whereby the members will maintain the flexible means taut at all periods.

5. A temporary binder comprising two members mo-vably connected together, and flexible means for holding the leaves having the ends thereof connected to one of the members and said means being in engagement with the other member whereby the members will maintain the flexible means taut at all periods.

6. A temporary binder comprising two members movably connected together, and flexible means for holding the leaves connected to one of the members and passing through the upper edge of the other member and thence down and around the lower edge thereof, whereby the members will maintain the holding means taut during all movements of the member and at all periods.

In testimony whereof I afiix my signature, in the presence of two witnesses.
